I guess you're going to get your wish of going to a slaughterhouse. A career slaughterhouse, that is.

It was at this moment that OP knew…they ****** up.

You sound horrible. You suck bad. Can you hear your job dying?

Not being an a-hole or keeping your mouth shut is free. Being an a-hole, it turns out, will cost you your paychecks.

you're an idiot and deserve your impending firing since you didn't check your surroundings before opening your mouth

I bet you didn’t sing. I will always respect a person that sings because for many there is a lot to overcome just in picking up the mic.

I don't really see the relevance of you bashing a song-performance to your employment-contract (in my country if this led to you being fired that would with absolutely no doubt be an illegal firing). But I do see the problem of your attitude that you felt the need to talk shit about coworkers. That is not contributing to anything positive, and I think it's fair to be reminded about that. From that to termination on the other hand is just a sign of a sick powerbalance between employers and empolyees

I take it you don't know how karaoke works. you go up there to have fun. it doesn't matter if someone sounds bad. your an asshole.
